ters Patent:

the bucket 10 as to permit of the ring22 being readily grasped by the bucket is raised for again hooking said In order to limit the upward swing of the for receiving the ring 22, suitable limiting means are provided, said means preferably consisting of a short length, of cable 26 sebucket 10 by shackles 27 or the like, the said cable '26 passing through a transverse hole suitably enlafving thus described my invention I claim asnew,

Lf-In a bucket of the class described, a bucket body, a bottom for said bucket con- .nected therewith todump by gravity, pivoted means on the bucket for connection with a lowering and hoisting cable, and -means connected with the dumping bottom and detachably engaging the. first-mentioned means to subject said first, means to the load imposed on thedumping'bottom and exert a downward pull on said first means,

said second means being adapted to completely detach itself from the first means when said first means is relieved of the weight of the load by the bucket coming to rest in the lowered position. i.

2.1T bucket of the class described having a dumping bottom, a lever ful'crumed on the bucket and provi ed with cable'attaching means, and an element connected with said a bottom and adapted'to detachably engage the said lever closed position.

3. A bucket of a bucket bottom and a. bail, a lever pivoted at one end onsaid bail and provided, be-

tween the ends of said lever, with means for connection with a cable, said lever bedrop when'the cable is reweight of 1 the bucket,- and adapted to be swung upwardly by the cable when the" latter is subjected -to the weight an element connected with of the bucket,

4. A bucket of the class described having a dumping bottom and a bail. a lever pivotci at one end.on said bail, and provided, between the ends of the lever, with means for connection with a cable, said lever being adapted to drop when the cable is relieved of the weight of the bucket, and to be swung upwardly by the cable when the latter is subjected to the weight of the bucket, an element connected with said di'imping bottom, means to detachably engage said ele-, inent with the lever at the opposite end from the pivot, and means independent of said and to be swung upwardly .by the cable when the latter is subjectedto the weight of the'bucket, an element connected with the dumping bottom and extending upwardly therefrom, means on said element at the upper end to detachably engage the lever at the opposite end from the pivot, said element when released from the lever being adapted to be carried downward by the bottom when dumping, and co-acting means on the bucket and onsaid element to arrest the downward movement of said element. and limit the downward movement of the said bottom.-

6. A bucket of the class-described having a dumping bottom and-a bail, a lever pivoted at one end on said bail, andprovided, between the ends of the lever, with means for connection with a cable, said lever be ing ada )ted to drop when the cable s relieved o the weight of the bucket, and to be swung-upwardly by the cable when the latter is subjected to the weight of the opposite the pivot, and a'flexible element secured at its opposite ends to the bucket, 1
